Illinois a corporation of Application May 16, 1932. Serial No, 611,559 8 Claims. (01. 56-20) The present invention relates generally to agricultural implements, particularly to such imple ments or machines as combines, and is particularly concerned with a new and improved manner and means for arranging the machine for transport.

In such agricultural machines as combines and the like there is generally provided some form of harvesting or operating unit which projects later- 10 ally for some distance with respect to some other part of the machine such as, in the case of combines, a thresher unit. When such a machine is to be transported it is quite desirable to materially reduce the overall width of the machine so that the same can conveniently be transported from one field to another, through gates, narrow lanes and along roads and highways.

Heretofore such reduction of the overall width of these machines has been effected by detaching the laterally projecting unit and arranging the same for ransport in a trailing position in rear of the remainder of the machine. In the case of combines, the harvester unit, that is, the laterally projecting platform andreel structure, has

been detached and mounted upon a wheel sup- 1 ported transport truck with one end of the operating unit connected with or supported upon the thresher unit of the combine. Generally this last named step has been accomplished by providing such sort of draft member connected with the wheel supported transport truck at one end and at its other end the draft member is connected with the thresher unit.

In such machines as combines embodying later- 5 ally projecting harvesting units as mentioned above, it is generally customary to provide some form of laterally projecting supporting member upon which the operating parts of the harvester unit can be supported, and in arranging these machines for transport, particularly where the platform and associated structure of the harvester unit are pivotally or otherwise movably connected with the laterally extending supporting member, means must also be provided to carry the supporting member. This has heretofore been 1 accomplished by carrying the supporting member upon the transport truck.

l-Ieretofore, these transport trucks have embodied a considerable number of parts and which necessarily have been made rather heavy in order to carry the entire weight of the harvester unit the associated supporting member therefor.

Having in mind these factors, the present invention has for its principal purpose the provision of a new and improved manner and means for arranging such agricultural machines for transport which involves only a very small number of parts and which are easily and conveniently attached and removed. More specifically. c the present invention'contemplates the provision of oneor more transport wheels, each provided with its own stub axle, and a draft member in the form of a draft tongue, all adapted to be separately connected with the frame of the operating unit, in connection with means for detachably carrying the supporting'member which normally projects laterally from the thresher unit and supports the platform and reel unit.

Other objects of the present invention include 7 new and improved mountings for the axles of the transport wheels by which the harvester or platform and reel unit is supported thereon, and a new and improved of draft tongue separate from the transport wheels and directly connected with the platform or harvester unit.

These and other objects and advantages of the present invention will be apparent from the following detailed description of the preferred structural embodiment, taken in conjunction with the accompanying drawings illustrating such embodiment, in which:

and

Figure 9 illustrates the detachable connection of the outer or grain wheel with the laterally outer -outer or'grain wheel 21. :ber 11 is braced by a diagonal brace pipe 25, one I end of the supporting member for the platform of the combine.

Referring now more particularly to Figure 1, it will be observed that I have chosen to illustrate the present invention as embodied in a combine including a grain tank 1, a thresher unit 2 and a harvester unit 3. The harvester unit 3 is representative of any form of laterally projecting operating unit carried by an agricultural machine and includes a suitable framework 5 on which is mounted a platform conveyor 6, an upwardly extending conveyor 7 leading into the feeder house of the thresher unit 2 and a reel 8, together with suitable operating mechanism for these parts.

The platform 5 and associatedstructure are connected in laterally extending relation with the thresher unit 2 by means of a supporting member in the form of a pipe 11. This member is connected with the thresher unit 2 through a universal joint 12 the inner section of which is journaled upon the outer end of the axle of the thresher unit, just outside the supporting wheel 13 for the thresher unit. The inner section of the universal joint 12 includes an arm 14 which is connected bymeans of'links 15 to one end of an assembly of balancing springs 1'7. The other end 10f the-spring assembly 17 is threadedly connected with an adjusting screw 18 including an oper-- zating crank 19, the adjusting screw being suitably anchored toithemain frame of the thresher unit, wherebyangular displacement of the universal ijoint '12 and the balancing arm 14 is resisted by thetension' Ofith springs 1'7.

The inner.- end of the lateral supporting member .11 is connected to the universal joint 12 while 'the outer endithere'of is supported by means of an The supporting memrend of the latter being suitably anchored to the fmain frameof Jthe thresher unit while the opposite end is connected with the outer end of the :supporting member 11 Many suitable means.

Preferably the connectionsbetween the diagonal member and themain'frame of the thresher unit'and'the supportingmember 11 are detachable, the detachable connection between the diamnal brace bar 25 and the outer end of the lateral supporting member 11' being effected by a suitable bracket 26-to which the end of the diagonal brace pipe is bolted, as indicatedby'the reference numeral 29. The universal'joint 12.also comprises separable parts connected together by bolt means or other means capable of being detached.

The platform5 and associated structure is nor- -mally, when the machineisin operation, carried for pivotal movement about an axis on supporting2arms-32 and 33, the forward-ends of which are pivoted to the frame of the platform 5, as

indicated by-the reference numeral 3% in Figure 6, while the other end of each of the supporting arms 32 and 33 is rigidly connected with the supporting pipe 11. Inthis way the weight of the platform 5 is normally balanced by the springs v17, since the weight of the platform normally tends to swing the supporting arms. 32 and 33 downwardly abouta transverse 'axis,which rocks the'supporting member 11 and the balancing arm "14, this movement being resisted by the tension inthesprings 17. The'magnitude of the tension in these springs can be adjusted by rota g the crank "19. The supporting arms 32 and are reinforced by suitable braces 46 and 41, and the platform 5 is steadied upon its pivotal support by means of adjustable links 43 and 44 the'in- (ner ends of which are connected directly to the platform while the other ends are connected to arms 46 and 47 journaled on the supporting member 11. These arms are, in turn, braced by rearwardly extending rods 49 and 5% connecting the arms 46 and 47 with the diagonal brace member 25. The outer arm 47 is connected to the collar 26 to which the laterally outer end of the diagonal .brace member 25 is bolted.

I have described above the supporting means for the platform when the latter is arranged for operation. When the machine is to be transported it is desirable to detach the platform 5 and the supporting means therefor so as to materially reduce theoverall width of the machine, and in order to arrange the machine for transport it then becomes necessary to provide means for supportingthe platform and other parts removed in such a manner that they can be drawn behind the thresher unit when the latter is transported.

The supporting means for the platform 5 can be detached from the frame of the thresher unit 2 by removing the bolt which holds the two parts of the universal joint 12 together and by disconnecting the bolts which connect the rear end of' li the diagonal brace member 25 with the frame of the thresher unit. It is preferable, however, before these'parts are-detached to release the tension of the springs 17 by turning the crank 19 in the proper direction, and before this is accom-i plished it is desirable to provide some form of support for the platform 5, such as blocks or the like sothat when its supporting means is detached the platform will be disposed in a position enabling the convenient attachment of the 1 transport means which tail later.

After the diagonal bar 25 and the supporting member 11 has been detached from the main will be described in deframe of the thresher unit 2 the diagonal brace bar 25 is detached from the supporting member 11 by releasing the bolt means 29 and detaching the brace rods 29 and 50. It is also desirable at this time todetach the grain wheel 21. As best shown in Figure 9 this wheel is carried upon a spindle which is secured to a saddle 56, the latter being detachably connected to the outer end of the support 11 by bolt means 5'7. When the bolt 57 is detached the wheel 21 and spindle '25 may be removed from the support 11;" In order I to permit the convenient attachment of the transport-wheels and associated structure it may be necessary before the supporting pipe 11 and brace ,member 25 aredetached to raise the platform 5 slightly above its normal position so that sufi- -cient blocking may be had to maintain the platform at a height sufficient to provide for the convenient attachment of the transport wheels.

The present invention is primarily concerned with the provision of a simple and inexpensive means for supporting the platform during transport. This means will now be described. By the present method, only two wheels 62 and 63, each having a short stub axle 65, and a relatively short wheels being journaled on the lower or journal portions of the axles 65. The journal portion and the shank portion of each axle is suitably braced by a bar 68 arranged diagonally as best shown in Figure 4.

The stub axles '65 are entirely separate and dis 15C nected with the frame of the platform5.

-- provided with a pair of sockets or sleeves 59 into a which the shank portion 67 of the axles are dis- For removably receiving the axles 65 the platform 5 is posed. In order to prevent the axles 65 from rotating in their mountings the shanks 67 are preferably of square cross section, see Figure 6, I and the axle receiving openings of the sleeves 69 are similarly formed square in cross section. The

sockets or sleeves 69 are formed in the following manner. The platform frame 5 includes a transverse angle bar and to this member a depending plate 81 is rigidly secured, as by welding or the like, the plate 81 being preferably secured to the upper edge. of the angle iron 00. A small strip 32 is welded to the edge of the depending flange of the angle iron 80 andthe lower edge of the plate 81 is bent inwardly in spaced relation with respect to the strip 32 to provide a The sleeves 69, as best shown in Figure 3, are arranged one adjacent each side of the platform 5 and are disposed adjacent to the longitudinal members constituting, together with the transverse frame member, the framework of the platform 5. The slot 85 may or may not extend the entire length of the sleeves 69.

The axles of the transport wheels are adapted to be readily inserted into and removed from the sleeves 60. In order to detachably secure the axles within these sleeves the present invention contemplates providing spring pressed plungers or latch members in the form of U-bars having one end adapted to be projected into registering openings formed in the sleeves andin the cooperating portions of the axles. As best shown in Figures 4 5 each of these latch members comprises a rod 90 bent in the form of a U, one end being somewhat longer than the other. The long .end of the U-shaped latch 90 is received within an opening formed the vertical flange of the transverse frame bar and a spring 91 is mounted on this end of the latch 90, being biased between the flange of the angle bar 80 and a washer 92 held onto the end of the latch 90 by means of a pin 93 or the equivalent. The other end of the U-shaped latch is pointed, as indicated in Figure 6 by the reference numeral 95, and this end is adapted to be projected through an opening 96 formed in the plate 31 and an opening 07 formed in the inner end of the shank 67 of the axle 65. As is apparent, when the openings 96 and 97 are in registry the spring 91 is operative to move the end 95 into the opening 97 in the axle, thereby effectively securing the axle in its mounting sleeve. Since the mounting for each of the transport wheels 62 and 63 is the same a description of one of them will sufhce.

Mention has been made above that the present invention contemplates carrying the supporting pipe 11 upon the frame of the platform when the latter is arranged for transport. The means provided for this purpose is best shown in Figures 6 and '7. It will be remembered that the bars 32 and 33 are pivotally connected at their forward ends with the platform 5 and are rigidly connected at 'their. rear ends with the supporting member 11.

To carry the member 11 on the platform, a pair of links or hooks 95 and 96 are provided. These hooks 95 and 95 pivotally connected to certain of the transverse frame bars making up the frame of the platform by means of bolts 9'? and 98. Any form of means for pivotally connecting the hooks with the frame of the platform is sufficient, pronearer one end thereof than the other.

hooks to be engaged underneath the lower edges of the arms 32 and 33, as indicated in Figure 7.

Obviously, when these hooks are engaged underneath the arms 32 and33 downward swinging of 80 the arms relative to their pivotal connection with the platform will be prevented and the supporting member 11 thus carried in a simpleand sturdy manner.

Referring now more particularly to Figure 2,? it will be observed that the transport wheels 62 and 63 with their axles 65 are'disposed intermediate the ends of the platform 5 and are somewhat This throws a slight preponderance of weight on the Q latter end of the platform. This is the end, therefore, to which it is desirable to connect the transport tongue or draft member '66. The tongue 66, as best shown in Figures '7 and 8, comprises a length of pipe or tubularstock having a. pin fixed to the end thereof. The pin 100 therefore serves as a reduced end of the draft tongue 66 and is adapted to be interengaged with certain parts of the platform 5. For this purpose the platform carries a bracket 101, preferably se-' 1() cured to one of the transverse frame bars, and this bracket includes a pair of spaced ears 103 and 10 1, the former being apertured to receive the pin 100. The bracket 101 may be secured to the platform by riveting, welding or the like. A1105 small lug is welded to the top of the pin 100 is received between the spaced ears 103 and 10s, the purpose of the lug being to hold the tongue 66 against endwise movement with respect to the platform and to transmit draft thereto? when the tongue is in position.

The transport tongue 65 is applied by first inserting the reduced end 100 in the aperture in the flange 103 and then rotating the tongue until the lug 105 is disposed between the ears 103 andi'u5 104. To hold the tongue in this position a spring latch is provided which comprises a rod or plunger 110 slidably supported in aligned perforations'in lugs or brackets 111 and 112 welded or otherwise secured to the top of the tongue 66. The brackets lll'and 112 are so disposed longitudinally of the tongue and relative to the pin 100 that they lie on opposite sides of a depending flange of one of the transverse angle irons 113 constituting the frame of the platform 5. hole is provided in the flange of the frame member 113 for the reception of the pin or plunger 110. The latch is normally held in position with the pin engaging the opening in the frame member 113 by means of a compression spring 115 disposed between a washer 116 on the rod 110 and a lug 117 welded or otherwise secured to the tongue, this lug also having an openin slidably receiving the rod 110. As is apparent, when the rod 110 engages the frame member 113 the tongue 66 is held in position and cannot rotate enough to free the lug 105 from between. the bracket ears 103 and 104. When it is desired to detach the transport tongue 66 it is a simple matter to pull the rod 110 out of the opening in the frame member 113 and then rotate the tongue 65 sufficiently to release the lug 105. Then the tongue may be drawn'from the opening in the apertured bracket 101.

The operation is believed to be apparent from the above description. The machine is shown in F1 'ure 1 as arranged for operation in the field. When the machine is to be arranged for transport, the members 11 and 25 are disconnected from the thresher' unit. 2 after first blocking up the platform 5 and releasing the tension in the gaged underneath the arms 32 and 33, it being a relatively simple matter to accomplish this after first detaching thegrain wheel 21 and.

32 and 33 can be carried separately by disconnecting the latter from the platform by removing the pivot bolts 34. Then by detaching the links and the diagonal brace 25, the pipe mem 'ber 11 can be carried on the thresher by swinging the same around approximately degrees without disconnecting it from the universal joint 12. It should also be noted that, if desired, after disconnecting the harvester platform 5 by removing the bolts 34 and disconnecting the links 43, the transverse pipe member 11, with the diagonal member 25 left connected to it and with the grain wheel 21 left in position, could be swung upwardly as a unit about an axis passing through the universal joint 12 and the pivotal connection of the rear end of the diagonal brace member 25 with the thresher frame and into a vertical plane.

After the pipe member 11 has been positioned as outlined above, the transport wheels 62 and 63 are attached to the sides of the platform by inserting the axles, respectively, into the mounting sleeves 69 until the openings 96 and 97 are in registry. When this is done the latches 90 can be engaged in these openings, whereupon the transport wheels will be detachably but securely fastened to the platform tosupport the same during transport. The transport tongue 66 is conveniently attached by first inserting the reduced end 100 into the opening in the ears 103 and then rotating the tongue to bring the draft transmitting lug 105 in between the ears on the bracket 101. To hold the tongue in this position the latch 110 is inserted in the opening in the transverse frame member 113. The forward end of the'tongue is then secured in any manner desired to the rear end of the thresher unit 2, whereupon the entire machine can conveniently be transported from one field to another and through narrow gates, lanes and the like.

. While I have shown and described in detail the preferred structural embodiment of the present invention, it will be apparent to those skilled in the art that my invention is not to be limited to the specific means shown and described but that, in fact, widely different means may be employed in the practice of the broader aspects of my invention.
